GEM. SETTING.

Application fi led May 25,

To all whom it may concern: v a

Be it known that I, JOHN A. ODoNNELL,

of Rochesteig inthe county of Monroe and State of NewYork, have inventedcertain new and useful Improvements in GemSettings, of which the following is'a specification.

The present invention relates to gem settings and an ob ect of the mventlon to provide a simple and inexpenslve construc- .tion which will make it possible for the ordinary jeweler to set diamonds and other precious stones in rings or other jewelry without requiring any great skill on hlspart.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claim.

In the drawings: I Fig. 1 is a plan view of a ring embodying the present invention;

Fig. 2 is a section on the line 2-2, Fig. 1; Fig. 3 is a section on the line 33, Fig. 2; Fig. 4 is a section on the line 4-4, Fig. 3; Fig. 5 is a plan view of another embodiment of the invention; Fig. 6 is a section on the line 8'--8,Fig. 5; and Fig. 7 is a perspectiveview of'the sleeve member of the ring setting, shown in'Fig. 6. j j

Referring first to the embodiment of the invention illustrated in Figs. 1 to 4, 1 indicates. the ring which has an opening 2 formed. therein with notches 3 on opposite sides of the inner end of the openings. Adapted to be fitted in this opening 2 is an outer sleeve or tubular member 4, which is internally threaded and has at its outer end an annular external flange 5 seating on a fiat'surface 6 formed on the ring 1 about the opening 2. v The sleeve or tubular member 4 also has an internal projection flange 7 at its outer end which is bevelled on its inner side and forms a seat for the gem 8. The diameter of the openings formed by the flange 7 varies to correspond with the size of the gem. The manufacturing firm may provide the jeweler with a numberof difl'erent tubular members 4 with flanges 7 of different sizes. The flange 7 may also be made so as to produce an opening of minimum size and be cut" by the jeweler-to fitthe gem. .After the tubular member 4 has been selected or plate.

. cut to provide the proper size opening within the internal flange 7, thetubular member is fitted within the ring body 1 and for this purpose the tubular member has lugs 9 onopposite sides which are bent outwardly into the recesses or notches 3. in the ring body at the innerend of the openings, thus securing the tubular or clamping member inplace in the ring body. Then the gem is fitted in f the tubular member and a ring 10 is loosely fitted in the tubular body to cooperate'with the faceof the gem opposite the facev en gaged by the fiange7. Thereafter an externally threaded ring 11 is introduced in the tubular member 4 to engage with internal threads of the tubular-member andabut the it ring 10. The ring 10 prevents any scratching of the jewel by the externally threaded ring 11 in the turningof the latter in thef tubular member 4.

A different type of ring body 1" is illus trated in Figs. 5 to 7 inclusive. This ring body has a plate '12 secured thereto andthis platehas .an opening therein form'e'dwith notches in opposite walls. A tubular mem- ;ber 4 is fitted in the opening of'the plate 12' and has afiange 5 seated against the top face ofthe plate. Opposite "sides of the tubular member are provided with, .ribs 9, which fit in the recess in the opposite walls of the openings in the plate 12 and these ribs are free at their lower ends froln-the a tubular member 4 so that they may be bent laterally at 9 as shown in Fig. 6Qto cooperate with the under face of the plate 12, in i order to hold thetubular member 4 in the The tubular member 4". has. at its outerend an internal flange 7 which may a be divided in different sizes or may form a gem opening of minimum diameter and may be cut tothe-size desired for the gem 8. This flangecooperates with one face. of the jewel 8, whilethe opposite side of the jewel is en VVhat I' claim as my invention and desire,
